Description

The present invention is, for example, dust, bacteria (including viruses), CO, CO2, ethylene gas, PM2.5 or less floating in indoor spaces such as hospitals, elderly / health facilities, smoking areas, construction sites, mechanical chemical factories, etc.・ Fine particle water is sprayed into the space mainly toward fine contaminant particles of 10 μm or less such as oil smoke, smoke, formaldehyde, odor, cesium, VOC, etc. . Thus, the present invention relates to an air purification system that purifies indoor space, further removes contaminants from the collected air to obtain fresh air, and repeatedly sprays fine particle water again.

Conventional purification of polluted air includes replacing the air in a room or a predetermined space with fresh air, and an electrostatic precipitator, filter device, humidification purification, plasma cluster type, etc., but these drawbacks are around the equipment. This space only has a purification effect, and the entire space cannot be purified.

In the conventional air purification system described in the section 0002, there is no product on the market that can remove contaminants of 10 μm or less. Further, it is not applied to removal of ultrafine particles such as CO, CO2, CH4, cesium, virus, oil smoke, VOC, etc. other than dust particles.

The conventional humidified air purification system generates water particles by colliding high-pressure air with water and sprays it into the room. The water particle size is larger than 10 μm and has no effect of diffusing into the room. It is a well-known fact that it is possible to eliminate this. Thus, it is said that there is no effect of removing the entire space. This method uses a two-fluid nozzle having two air and water inlets for the nozzle as a means, for example, an air pressure of about 0.5 megapascals and an air amount of about 15-20 l per minute per nozzle. This is due to the technology that particles water into a room or a predetermined space. In this case, water particles having a water particle size of about 10 to 30 μm or more are ejected, and fine suspended contaminants cannot be adsorbed and removed.

A partition is provided and a space is formed by the partition plate, and the air intake side sucks and purifies contaminated air containing nano fine particle water adsorbing fine floating contaminants such as dust from the outside space of the apparatus, and purifies it at the outlet of the water smoke tank A smoke generator that generates water smoke from nano-particulate water using water pumped out from a nozzle at the tip of a water supply pipe connected to the water supply tank in the device space The air purification system is characterized by spraying the water smoke together with fresh air.

Further, the present invention is characterized by an air purification system in which a suction fan is provided in the air intake port and a water smoke outlet is provided.

Further, an air flow pipe control venturi partition wall 9.10 suspended from a position in contact with the ceiling surface of the casing is formed with a space in which an air flow passage is formed on the bottom plate side of the casing. An intermediate partition rising from the position of the sedimentation chamber / reservoir water surface on the bottom plate side is formed between 10 air flow pipe control venturi partitions, and the air is meandered in the vertical direction by the air flow pipe control venturi partition of 9.10. It features an air purification system that forms a flow passage.

Further, the nozzle is fixed to a metal fitting provided in the spray chamber / air purification chamber, and air purification is provided with a sphere that forms nano fine particle water by collision of spray water from the nozzle at a position away from the tip of the nozzle.

Further, the contaminated air is purified by removing fine pollutants such as dust, odor and gas by spraying and mixing the contaminated air in the sedimentation chamber / reservoir tank on the bottom plate side of the casing. It is characterized by an air purification system that drains water from the outlet and replaces it with fresh stored water from the water tank.

The air purification system of the present invention sprays fine particle water of 10 μm or less into a predetermined space in the form of water smoke to adsorb and capture fine pollutants floating in the predetermined space, and purifies those fine contaminants as air. The predetermined space can be always made fresh by taking it into the apparatus and removing it, and spraying the nano fine particle water again on the predetermined space together with fresh air from which the contaminants have been removed.

The conventional air purification system has a problem in effect because air does not spread over the entire space. However, it was possible to purify the space around the equipment. The device of the present invention has a particle size of nano fine particle water of 1 nm to 10 μm or less. In particular, since the movement speed of the particle size at the water molecule level is Mach 1-2, the entire space can be purified from the large diffusion effect due to the characteristics of the physical chemistry at the molecular level.

It has been confirmed that the air quality is remarkably improved together with the effect that the air purification speed is fast because the purification of the entire space is possible and the temperature and humidity of the predetermined space are uniform.

Furthermore, the above-mentioned suspended contaminants of 10 μm or less suspended in a predetermined space are easily adsorbed with nano-fine particle water having approximately the same particle size or particle size of 10 μm or less, so that these fine suspended contaminants can be efficiently removed. Became".

In addition, since each device constituting the air purification system of the present invention can be easily assembled at the site and can be moved and installed, even if the predetermined space is a space that moves like a construction site, the minute generated. It became possible to remove airborne contaminants.

The following graph shows the effect of the air purification system using this device.

  It is FIG. 1 for implementing this invention. Top view of the device   It is FIG. 2 for implementing this invention. Overall view

The best mode for carrying out the present invention will be described below with reference to the drawings.

FIG. 1 shows the entire air purification apparatus constituting the air purification system of the present invention. The air purification apparatus 1 has a substantially square casing that includes a bottom plate 21, front and rear side walls 19.20, left and right side walls 17.18, and a casing 2, and is configured to nanoplot fine pollutant suspended substances in a predetermined space. A spray chamber / air purification chamber provided with a smoke generating device that takes in and purifies together with fine particle water, and sprays freshly humidified air from the purified air and fine particle water as smoke to a predetermined space, and the spray chamber It also comprises a water tank 12 and a drain tank 25 for supplying water to the air purification chamber.

The spray chamber / air purification chamber 6 hangs down from a position in contact with the ceiling surface on the back side of the housing 2 and has a space on the lower side, and has a space on the upper side between the venturi partition walls 9.10 for air flow control. The lower partition wall 11 having the lower partition wall 21 is formed by providing a communication space for stored water on the bottom plate 21 side, and the partition wall forms a space of a half partition wall. The contaminated air taken into the spray chamber / air purification chamber 6 sequentially moves from the upper side to the lower side and from the lower side to the upper side in the above space.

The contaminated air in the predetermined space is taken into the spray chamber / air purification chamber 6 from the air intake port 3 formed in the housing 2, but the air is forced by providing the fan 5 at the air intake port. Efficiently.

The depth of the storage tank on the bottom plate 21 can be effectively removed by setting the water level height of the storage tank arbitrarily according to the type, component, size, concentration, etc. of the contaminated air. It became possible. For example, it is a feature of this apparatus that general dust (particle diameter of about 10 μm or less) can be set to 30 mm, and ultrafine dust (particle diameter of 1 μm or less) can be set to 50 mm.

The above-mentioned storage water tank is stocked with a certain depth of 30 to 60 mm, and at least the upper surface of the stored water, the air flow pipe control venturi partition wall of 9.10, and the air flow intermediate of 11 An air flow passage 22 is formed between the partition walls, thereby forming a space.

On the other hand, the lower partition wall 11 rises from a position where the water tank of the bottom plate 21 is substantially water surface, and is attached to the front and rear walls 19.20 so that the air flow passage 22 is formed on the upper side.

The polluted air is taken into the spray chamber / air purifying chamber 6 from the air intake port 3, and the side wall 17.19.20 forming the side wall casing forming the casing and the venturi partition wall 9. Are guided downward in the 22 air flow passages formed by the above and are strongly blown to the reservoir and mixed with the reservoir. As will be described later, the contaminated air is taken into the spray chamber / air purification chamber 6 in a state where the fine particle water and the contaminated particles floating in the predetermined space are adsorbed. It is often mixed.

The air from which the contaminants adsorbed to the fine particle water have been removed as described above flows between the stored water and the air flow path 22.23 between the air flow pipe control venturi partition 9.10 and the partition plate 11 in the middle. And is guided to the space of the clean air chamber 7. The water supply pipe 14 has a nozzle 15 formed at the tip thereof. The nozzle 15 is fixed to one end of a round bar metal fitting 15a.

The water squeezed out from the nozzle 15 collides with the sphere 16 to generate fine particle water, which is sprayed onto the clean air chamber 7 as the second space.

The contaminated air taken into the spray chamber / air purification chamber 6 is the above-mentioned 6. Or the spray cleaning chamber space of 7 is mixed with the stored water to remove contaminants, and the air from which these contaminants have been removed passes through the air flow passage 22.23 in a meandering manner, and passes therethrough. In the process, heavy polluted air attached with contaminants descends to the stored water side and is removed, and fine particle water formed as light smoke is transferred to the air intake 3 from the smoke outlet 4 formed in the housing 2. The formed fan 5 is sprayed in a predetermined space together with fresh air by the forcing force of the fan 5.

The contaminated air is purified in the process of moving in a meandering manner in the space in the air purification chamber 6, and most of the contaminated air is purified at the portion having the nozzle 16. The water ejected from the nozzle 15 collides with the sphere 16 as described above. The water supply pipe 14 connected to the nozzle 15 has a diameter of about 14 mm, for example, and the nozzle 15 at the tip of the water supply pipe 14 has a diameter of about 0.2 mm. In this case, the pressurizing force of the pump 13 connected to the water supply pipe 14 is 1.0 Mpa, and water is jetted at a pressure of 10 kmp to collide with the spheres 16 separated by about 80 mm. This collision causes a lot of water to become fine particle water having a particle diameter of 10 μm or less, sprayed as water smoke, and floated and released.

Each of the above-mentioned water smoke is sprayed into a predetermined space from the water smoke outlet 4 together with fresh air by the forcing means by the fan 5. The sprayed fine particle water having a particle size of 10 μm or less is dust, bacteria, virus, CO gas floating in a predetermined space. CO2 gas, CH4 gas, PM2.5 or less, oil smoke, formaldehyde, odor / VOC, etc., are almost the same or slightly larger than the pollutant particle size. Will be integrated.

Also, the contaminants in the contaminated air taken into the spray chamber / air purification chamber 6 are mixed with the stored water and stored in the contaminated water tank 23 installed at the lower part of the apparatus via the drain pipe 24. Is done. Depending on the water level, the water is discharged to the outside by the pump 25 of the contaminated water tank.

The present invention cannot be solved by the conventional air purification function of hospitals, elderly facilities, chemical machinery factories, smoking areas, construction sites, plant factories, agricultural facilities, etc., for example, floating fine particles of norovirus in hospitals, elderly facilities, etc. Bacteria removal, chemical machinery factory VOC / oil smoke countermeasures, smoking area carbon monoxide and odor countermeasures, construction site toxic gas countermeasures, plant factory air purification and vegetable growth promotion / energy conservation measures, agricultural facility agrochemicals / growth promotion The range of use is wide-ranging for countermeasures, etc. Especially, from now on, this product has functions of both a safer work environment for humans and running costs, and the above market is considered promising.
